Arena is a platform for evaluating how AI models perform in real-world scenarios, founded by researchers from UC Berkeley's SkyLab. The company enables tens of millions of users monthly to evaluate frontier AI systems, and their data powers transparent, rigorous evaluations used by leading AI labs, enterprises, and independent researchers.
You will serve as a senior growth marketer responsible for defining and driving growth across Arena's products and business lines. This is a high-ownership, strategic role combining growth strategy, product thinking, analytical rigor, and hands-on execution.
Key responsibilities include:
- Identifying and building scalable growth programs across the full funnel (acquisition, activation, engagement, retention, conversion, monetization)
- Owning growth initiatives end-to-end: opportunity identification, strategy development, hypothesis formation, campaign execution, analysis, and scaling decisions
- Managing growth across multiple channels including SEO/AEO, paid acquisition, email, web, programmatic growth, product-led growth, launches, and emerging AI-native distribution
- Establishing measurement frameworks and owning growth KPIs with clear accountability for business outcomes
- Partnering cross-functionally with Product, Design, Engineering, Data, and Marketing to translate growth opportunities into shipped experiences and scalable systems
- Developing targeted strategies for distinct audiences: consumers, developers, researchers, AI labs, and enterprise customers
- Building repeatable growth systems and processes that allow successful experiments to scale
- Communicating strategy, performance, and insights to cross-functional partners and leadership
- Balancing strategic judgment with hands-on execution—writing, analyzing, building, QA-ing, launching, and iterating as needed
The role requires moving fluidly between setting strategy and executing tactically, with strong accountability for business outcomes and comfort operating in ambiguity.
REQUIREMENTS:
- 8+ years of experience in growth marketing, product growth, performance marketing, or similarly analytical and execution-oriented growth roles
- Proven track record of owning growth goals and driving measurable improvements in acquisition, activation, engagement, conversion, retention, or revenue
- Demonstrated experience taking growth initiatives from opportunity identification through strategy, execution, experimentation, measurement, and scaling
- Strong understanding of LTV, retention, monetization, and unit economics and how they inform growth strategy
- Experience owning KPIs and being accountable for campaign, channel, funnel, or business outcomes
- Experience building and scaling multiple growth channels with deep expertise in at least one area (SEO/AEO, paid acquisition, email, web, PLG, or programmatic growth)
- Strong experimentation mindset with experience designing tests, defining success metrics, interpreting results, and translating learnings into decisions
- Strong analytical judgment and comfort using data to diagnose problems, prioritize opportunities, and make decisions
- Ability to move fluidly between strategy and hands-on execution
- Comfortable operating in ambiguity, identifying opportunities independently, and taking accountability for results
PREFERRED QUALIFICATIONS:
- Experience growing developer, research, technical, enterprise, or AI-native products
- Growth experience at a high-growth startup or building a growth function from early stage
- Familiarity with the AI/ML landscape and curiosity about models, agents, benchmarks, and evaluations
- Experience building product-led and/or self-serve growth motions
- Experience developing new or unconventional acquisition channels
